Recycling of construction and demolition (C&D) waste is one of the most effective ways to develop sustainable pavements. In this study, the feasibility of using ceramic waste as an alternative source for fine aggregate to improve the polishing resistance of cement mortar is investigated. The recycled fine aggregates used in this study originate from sanitary ceramic waste; the physical and chemical properties of the Recycled Ceramic Aggregates (RCA) were determined. The optimal RCA content in the mortar was determined based on the mechanical strength of the resulting composite. The polishing resistance of coarse and fine RCA was characterized with the Polished Stone Value (PSV) test and the Wehner/Schulze (W/S) test, respectively. The test results indicate that the polishing resistance of RCA is significantly better than that of commonly used mineral aggregate. Lastly, the self-developed Aachen Polishing Machine (APM) was applied to validate the improvement of RCA on the polishing resistance of cement mortar under realistic loading conditions. The cement mortar containing RCA exhibits a better long-term polishing resistance than the traditional mortar. The results from this study provide insights into the application of RCA in concrete pavements and the improvement of material properties.

通过使用再生陶瓷提高水泥砂浆的耐磨性

循环利用拆建废料是发展可持续人行道的最有效方法之一。在这项研究中,研究了使用陶瓷废料作为细骨料的替代来源以提高水泥砂浆的耐磨性的可行性。本研究中使用的回收细骨料来自卫生陶瓷废料。确定了再生陶瓷骨料(RCA)的物理和化学性质。灰浆中的最佳RCA含量是根据所得复合材料的机械强度确定的。粗磨和细磨RCA的耐磨性分别通过“抛光石值”(PSV)测试和Wehner / Schulze(W / S)测试来表征。试验结果表明,RCA的抛光性能明显优于常用的矿物骨料。最后,使用自行开发的亚琛抛光机(APM)验证了RCA对在实际载荷条件下水泥砂浆的耐抛光性的改进。含有RCA的水泥砂浆比传统砂浆具有更好的长期耐抛光性。这项研究的结果为RCA在混凝土路面中的应用以及材料性能的改善提供了见识。含有RCA的水泥砂浆比传统砂浆具有更好的长期耐抛光性。这项研究的结果为RCA在混凝土路面中的应用以及材料性能的改善提供了见识。含有RCA的水泥砂浆比传统砂浆具有更好的长期耐抛光性。这项研究的结果为RCA在混凝土路面中的应用以及材料性能的改善提供了见识。
